WATER SEAL FOR CLEANING DEVICES.

Application filed October 15, 1924. Serial No. 743,849.

for its purpose. With the present invention the water seal is providedand renewed and circulated with each operation of the pan'so as tomaintain it in working quantity and also to refresh it. Features of theinvention will appear from the specification, and claims.

The invention is illustrated in the accompanying drawings as follows:

' Fig. 1 shows a side elevation, a part being broken away, of a bed pancleaner with my device in place thereon...

view of Fig; 1.

Fig. 3 a section on the line 3-3 in Fig. 4:. Fig. at a section on theline H in Fig. 3. 1 marks the case, 2. the cover, 8 the pipe supplyingwater, and 4 a branch extending from the supply] pipe 3 to the jet ring5. The ring 5 is rectangular in cross sectionand is secured tothe innerwall of the case near its top by welding, or other convenient means. Avalve l is arranged in the branch land controls the flow of the cleaningwater as it is delivered from the supply pipe 3 to the ring 5. The jetring is supplied with jet openings 6 and 7 for delivering water to a bedpan or articlewithin the case tor cleaning. A flush valve 8 is connectedto the supply pipe operated by a handle 9 and delivers water through apipe 10 to lower jets for further cleaning the article in the case. andcontrolled by a valve 12 for sterilizing the cleaned article. The .caseis provided with the usual discharge trap 1 and'vent A waterseal'recessring 13 is arranged Fig. 2 a similar view at right angles tothe Steam is delivered through a pipe 11 veniently formed by welding aband 13' to the inner face of the jet ring, the band forming the innerwall of the recess, the jet ring the lower wall ofthe recess and thewall of the case the outer wall of the recess. The i cover is providedwith a flange 14 which extends around the cover and into the recess ofthe seal ring 13 when the cover is closed.

WVater is delivered from the jet ring through a pipe 15, the pipe havinga discharge above the bottom of the flange 14 and the discharge being ina downward and tangential direction relatively to the ring as clearlyshown in Fig. 3. The effect of the discharge of water through the pipe15 is to overflow the seal recess and at the same time cause acirculation or annular movement of the Water in the recess. Thus thewater with each operation of the device is replenished and controlledconduit for introducing cleaning fluid into said chamber; a trougharranged in said. chamber about its upper edge; a cover for said chamberhaving a flange adapted to enter said trough; and means for conductingfluid from said valve controlled conduit to said trough.

2. In a cleaning device, the combination of an open-topped cleaningchamber; a valve controlled conduit for introducing cleaning fluid intosaid chamber; a trough arranged in saidchamber about its upper edge; acover for said'ch amber having a flange adapted to enter said troughyandmeans for conducting fluid from said valve controlled conduit to saidtrough, the discharge to the trough being'in a circumferentialdirection. j

In testimony whereof I have hereunto set my hand.
